Canadian Prime Minister Justin Trudeau refused to hold up a copy of the trade pact he signed with Mexican President Enrique Pena Nieto and President Trump at Friday’s ceremony, despite the latter urging him to do so.

Trudeau appeared to be in a bit of a feisty mood despite the historic nature of the agreement, along with Trump’s insistence that the two have become ‘great friends.’

Aside from being the only one of the three North American leaders to not hold the document up for a photo op, Trudeau referred to the President as simply “Donald” during the meeting, and repeatedly called the USMCA, Trump’s preferred moniker, the ‘new North American Free Trade Agreement’ (NAFTA) instead.

Trudeau refuses to hold up agreement for photo op

Trudeau, despite the President urging each of the world leaders to pose for a photo op, refused to hold up his signed version of the document.

Each of the men signed a copy laid out in front of them, then passed it along to the next to do the same. Upon all three signing, Trump declared, “We might as well hold that up.”

Nieto complied, while Trudeau refused, instead opting to smile for the cameras.

Trudeau refers to the new pact as ‘the new NAFTA’

At the signing ceremony, Trudeau also refused to call the pact by it’s official title – the United States-Mexico-Canada Agreement (USMCA).

He instead called it the “new North American Free Trade Agreement,” a passive-aggressive, petulant complaint to show his preference for the old NAFTA status quo, instead of the better deal demanded by President Trump.

It isn’t a minor snub either, as Trump’s insistence on giving NAFTA a new name was a key to negotiations.

A key non-negotiable U.S. requirement in the NAFTA renegotiations was that the revised agreement not be called NAFTA.

Trudeau’s official Twitter account also referred to the deal as the “new NAFTA” shortly after the ceremony.

“This is a model agreement that changes the trade landscape forever,” Trump bragged. “This is an agreement that first and foremost benefits working people, something of great importance to all three of us here today.”
